Is there a reef safe sponge eating fish?

My tank seems to have been recently infiltrated with small (but getting larger) yellowish sponges. I thought I had read once that there is a fish that is reef safe that would eat them, much like the copper banded butterfly eat the nuisance anemones. Is that true??

 

There are about 5000 species of sponges found throughout the world..Please take pics of these "sponges"

 

I thought I read where dwarf angels may eat sponges - but they are reef safe with caution

 

I'm not sure why you want to rid them. I can see them as being only beneficial

Maybe because they are unsightly? Here's a pix.

 

I think they are cool. Do not be surprised if they start to die back at some time. My tanks have gone through stages where sponges readily grew and then as the tank matured or changed the sponges just slowly faded away. A fish that eats enough sponge to solve your sponge problem is probably also a fish that you will have difficulty meeting that fishes dietary needs long term. Dwarf Angels are not the fish to acquire unless you want one for purposes other than possibly eating sponges.

 

Cool. I have the same. Also White and black sponges.

 

As always, great advice on this sit. Thanks to all.
